A Shiv generator that gets cheaper every use. First cast costs 2, second 1, third 0. If the card cycles back a few times, it eventually mass-produces 3–4 Shivs for no energy. With Accuracy, it delivers 3–4 buffed Shivs per 0-cost play — a relentless Shiv-deck engine. Early casts are heavy, but scaling makes late-fight efficiency extreme. A long-fight specialist.

• The first cast is heavy at 2 cost. Cast aggressively so the cost ramps down quickly.
• After 3 uses it becomes 0 cost — from then on, 3–4 Shivs per turn for free.
• With Accuracy, once discounted, Ace in the Sleeve pumps out buffed Shivs in volume for huge damage.
• With Finisher, Ace in the Sleeve → fire Shivs → Finisher is a natural pattern.
• Upgraded generates 4 Shivs — once discounted, supply explodes further.

• Accuracy: +4 Shiv damage. Once discounted, a flood of 0-cost buffed Shivs equals big damage.
• Finisher: damage per Attack played. Ace in the Sleeve supplies Shivs, Finisher closes.
• Infinite Blades: Shiv at turn start. Combined with Ace in the Sleeve, Shiv supply is constant.
• Knife Trap: play all Exhausted Shivs. Ace in the Sleeve's Shivs → Exhaust → Knife Trap recycles them.
